Quick answer: Closing a credit card usually lowers your score temporarily because it reduces your total available credit (raising utilization) and may shorten your average account age. The impact varies by your overall credit profile.
Key Takeaways
- Credit utilization—the percentage of available credit you use—jumps when you close a card, often dropping your score 10 to 50 points
- Closed cards remain on your credit report for up to 10 years if positive, so average age of accounts does not drop immediately
- FICO versions 8 and 9 count closed accounts toward length of history until they fall off your report per Fair Credit Reporting Act 15 U.S.C. § 1681c
- Closing your oldest card eventually shortens your credit history once the account ages off, potentially lowering your score further
